You neglected to say what the roll pin aligned. If the roll pin is the proper size then alignment should be correct since in most cases this is their function. A
to small or damaged pin can cause misalignment. A good Mechanic would have been aware of either case and would not have chanced a misalignment.

For the past month I have been trying to get several contractors to do some minor work for me. After an initial visit and price quote, we set up a time for the work to be done. Either they call and postpone or just don't show up at all and don't return phone calls.

I called a collection agency to get them to contact some of the businesses past due accounts. They never called me back.

Last night I had an appointment to meet with a realtor at a house I wanted to buy---the agent was a no show.

Ecclesiastes 3:1

The clock of life is wound but once and no man has the power
To know just when the hands will stop - on what day, or what hour.
Now is the only time you have, so live it with a will -
Don't wait until tomorrow - the hands may then be still.
